Answer:
Time= 1/frequency
=1/100
=0.01
Explanation:
Answer:
Order of 10^(-35) m.
Explanation:
The string theory is a theoretical concept whereby the very small particles of particle physics are replaced by one dimensional objects which are called strings. This theory is also applicable to black hole physics, nuclear physics, cosmology, etc.
Now, according to string theory, six space-time dimensions cannot be measured except as quantum numbers of internal particle properties because they are curled up in size of the order of 10^(-35) m.
This is because the length of the scale is assumed to be on the order of the Planck length, or 10^(−35) meters which is the scale at which the effects of quantum gravity are usually believed to become very significant.
Answer:
Net force = 250 N
Explanation:
Given that,
The mass of a teacher, m = 75 kg
As the parachute opens, the system experiences a 1000N drag.
We need to find the magnitude of net force acting on the teacher. 2 forces are acting on her i.e. drag force and weight.
Net force,
F = mg-D
= 75(10)-1000
= -250 N
Hence, the net force is 250 N and it is acting in the upward direction.
Now, it's pretty simple. And if you meant "amber" as in "amp" and "volt" and in "voltage" maybe. Then this is simple.
An ampere (or amp) is a measure of the amount of electricity, called "current," in a circuit, while voltage (or volt) is a measure of the force behind that electricity's motion.<span> </span>
Answer:
The object must be placed just ahead of focus towards the lens.
Explanation:
As we know that a magnifying glass is a convex lens and for the convex lens and for a convex lens we get the image virtual, erect and magnified only when it is placed between the optical center and the focus of the lens.
In that range when the object is nearest to the focus of the lens it has the maximum size.
So it can be possible if the object is placed at 9.98 cm from the optical center.
The largest image is formed at infinity when the object is placed at focus but it is not visible to the normal eyes.
